Approximately 15% of pediatric firearm injuries are unintentional. While demographic characteristics of unintentional firearm injuries have been described, the relationship between injury characteristics and mortality is not well understood. In this study, we identified injury characteristics associated with fatality among unintentional firearm injuries in adolescents.
We conducted a retrospective (May 2022-May 2023) cross-sectional study of unintentional firearm injuries among adolescents 12-17 years old using the Gun Violence Archive. Variables included victim age and sex, shooter age and sex, injury location, injury circumstance, number of firearms, type of firearm, firearm owner, census region, and shooter relationship to the victim. Logistic regression was used to identify variables associated with fatality.
Of 319 unintentional incidents, 212 (66.5%) were non-fatal and 107 (34.5%) were fatal. Of all shootings, 176 (55.2%) occurred in a residence. A shooter was identified in 256 (80.3%) cases; 43.0% of these were a peer of the victim. The adjusted odds of fatality were higher when a peer was the shooter (aOR 5.38, 95% CI 2.57, 11.80) compared to self-inflicted injury and when the shooting took place in the victim's residence (aOR 2.87, 95% CI 1.07, 7.88) or another residence (aOR 3.03, 95% CI 1.45, 6.67) versus a public location (Fig. 1).
Unintentional firearm injuries were more likely fatal when a peer was the shooter and when the shooting occurred at a residence. This amplifies the importance of safe home firearm storage and exploring other evidence-based approaches to decreasing youth access to firearms.
约15%的儿童枪支伤害是意外造成的。虽然已经描述了意外枪支伤害的人口统计学特征，但伤害特征与死亡率之间的关系尚未得到充分理解。在本研究中，我们确定了青少年意外枪支伤害中与死亡相关的伤害特征。
我们使用枪支暴力档案对12至17岁青少年的意外枪支伤害进行了一项回顾性（2022年5月至2023年5月）横断面研究。变量包括受害者年龄和性别、枪手年龄和性别、受伤部位、受伤情况、枪支数量、枪支类型、枪支所有者、人口普查区域以及枪手与受害者的关系。采用逻辑回归来确定与死亡相关的变量。
在319起意外事件中，212起（66.5%）为非致命事件，107起（34.5%）为致命事件。在所有枪击事件中，176起（55.2%）发生在住宅内。在256起（80.3%）案件中确定了枪手；其中43.0%是受害者的同龄人。与自我伤害相比，当枪手是同龄人时，死亡的调整后几率更高（调整后比值比为5.38，95%置信区间为2.57，11.80），并且与在公共场所相比，当枪击发生在受害者的住所（调整后比值比为2.87，95%置信区间为1.07，7.88）或另一住所（调整后比值比为3.03，95%置信区间为1.45，6.67）时，死亡的调整后几率更高（图1）。
当枪手是同龄人且枪击发生在住宅内时，意外枪支伤害更有可能致命。这凸显了安全存放家庭枪支以及探索其他基于证据的方法以减少青少年获得枪支机会的重要性。
